Do diesels run better hot or cold?

Yes diesel engines are more efficient than petrol or lpg engines. What this means in practice is they emit less heat, they turn more of their fuel into motion. However, this means they do not heat up as quickly in the cold as a petrol of equivalent size.

Is it bad for diesels to idle?

It is true that diesel engines use barely any fuel while idling, far less than a gasoline engine. While it isn’t particularly bad for it, there just isn’t much reason to do it; most diesels start perfectly fine when cold, warm up in a reasonable time, and don’t have gelling issues.
